children-oriented theme park for Kingman and Heritage islands. Mayor Dixon supported the idea, but Interior Secretary Lujan forced her to drop the idea because Interior officials felt the proposed development was too densely built-up and would destroy the character of the region. The company drew up new proposals in August 1991 that provided for fewer attractions.
